After finishing their meal, the three of them returned to the city. It was already getting dark.

Wu Chang and Amber had agreed to be home before dark. He assumed the day would end here for the two girls. To his surprise, the next stop for the car wasn't Grace's house, but Nokes Primary School.

Wu Chang shook his head, thinking Grace sure had an abundance of energy, still having plans?

In the dusk, Nokes Primary School appeared dark red under the sunset, emanating a sinister aura that wasn't present during the day.

Amber was already somewhat reluctant about Nokes Primary School. Seeing this, she was even more inclined to back out.

"Grace, it's getting dark. I promised Sean I'd be home before nightfall."

The driver, Mark, also chimed in:

"Grace, if you left something in the classroom, I can bring you back tomorrow."

Grace waved her hand dismissively and said, "I've timed it just right to be here now. Coming tomorrow would be pointless. Don't worry, Amber, it won't take long, and I guarantee you won't get scolded."

Seeing Grace's determination, Amber found it difficult to refuse and asked:

"Why did you specifically come back to school at this time?"

Grace straightened her chest, put her left hand on her hip, and pointed with her right hand at the old school building sealed off by yellow tape.

"I'm going there for an adventure!"

Amber and Mark both felt a chill.

Having graduated from Nokes Primary School, Mark was naturally aware of the old school building's rumors, and from his school days, it was a forbidden area for students.

He couldn't hold back as much as Amber could, and said, "Are you crazy! That's the old school building – it's really haunted!"

Amber's face turned grim as she looked at the yellow tape surrounding the old school building, recalling the harrowing memory when Wu Chang and Erin nearly met with danger.

Grace, however, was unfazed and said, "It's precisely because it's really haunted that I'm here. Aren't you curious if ghosts really exist in this world?"

The Mark, who had just mentioned ghosts, was now shaking his head vigorously, saying, "I only believe in science."

Amber, hearing Mark's words, hesitated slightly.

She actually wanted to know if people had souls and where they would go after death.

She thought of many people who treated her well, hoping they could enter the Celestial Kingdom after death.

Grace unbuttoned the top of her shirt, followed the necklace around her neck, and pulled out a silver cross pendant.

"No need to be afraid. If there really are ghosts, I can handle them with this. I borrowed this cross from my grandpa."

"It's said to be an antique, blessed by at least three popes. With it, my grandpa was never hit by a bullet no matter how dangerous the battlefield. Ordinary ghosts would melt upon seeing it."

"Doesn't the thought of personally performing an exorcism excite you?"

Wu Chang slapped his forehead. He knew Grace was heading straight into danger.

Fine, if she wants to risk her life, so be it, but don't drag my Amber into it.

At first, he wanted to step in and stop them, but when Grace took out the cross, he paused.

As soon as the cross appeared, the All-Knowing Crystal in his space stirred.

To make the All-Knowing Crystal move, there was only one possibility: the cross contained the Primordial Spirit Core.

Wow, Ms. Grace, didn't expect you to have the real deal. And it's so pure.

He really wanted to ask Grace where her grandpa got it from, because even if it were a cross used by the apostles, its gold content might not be higher than the cross Grace held.

Let me tell you, if Grace could unleash the cross's power, ordinary monsters wouldn't stand a chance against them.

He pondered for a moment and decided to follow them and see what would happen.

His intuition told him there was likely a problem in the old school building, and it was directed at Amber.

After dealing with the Mirror Killer and the luminescent fungus, he realized that Amber's Heart Demon could only be triggered by her, and neither he nor Erin could preemptively discover and solve the problem.

Now with the protection of the cross and his secret following, this might be a good opportunity.

They could draw out whatever was lurking in the old school building and seize the opportunity to eliminate a part of Amber's Heart Demon.

As Wu Chang made his decision, Amber and Mark had been persuaded by Grace, and the three headed towards the old school building.

Wu Chang followed them into the old school building.

As soon as he stepped inside, he narrowed his eyes. This time, the atmosphere was right.

The old school building at dusk was filled with an ominous aura, not a smell that could be described, but the air around instinctively made people tense and uneasy.

Previously, when he and Erin had entered, they hadn't encountered such conditions.

As he passed by the window-lined corridors, Wu Chang glanced outside and noticed something subtly off about the campus, as if what he saw were mere pictures and not the real campus.

When Amber and the others walked ahead, Wu Chang punched at the glass, but with his 36 points of Power, he didn't even crack it.

As expected, like the Mirror World and fungus blanket space, stepping into the old school building meant entering a separate dimension.

Having confirmed the nature of the space, he chased after Amber and the others.

Grace's target was the rooftop. The day building materials fell, she overheard a mysterious boy claim that a couple of days earlier, he saw a blurry figure on the roof of the old school building.

He insisted that the building material collapse was no accident, but the work of the ghost inside the old school building trying to harm anyone who passed by.
